Increase the Airflow to Your Vents in Rooms that are Too Cold

Is there a room in your house that is usually cooler or hotter than the others?

If so it is probably due to bad airflow from your vents. Airflow in central air homes weakens the further it travels through the ducts. The Tjernlund Cyclone Booster Fan Plus helps solves this problem. The Booster Fan boosts the idle air from vents outward into the rooms where it is needed most, making every room in your home equally comfortable. The innovative design features a built-in thermostat that senses heated or cooled air and turns the fan on and off automatically, lowering your heating and cooling costs year round. The Cyclone Booster Fan Plus helps SAVE ENERGY and MONEY, just set it and forget it.
Increases and maximizes ventilation in any room in your home
